Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung nahtloser Druckbehälter aus einem mit Aluminium beruhigten CrMo-Stahl bestimmter Zusammensetzung. Die Druckbehälter werden nach dem Warmumformen vergütet durch Austenieren bei 830 bis 880°C, Abkühlen bei einer Geschwindgkeit von 5 bis 15 K/s bis zur Raumtemperatur und Anlassen bis zu 680° C und Abkühlen an Luft. Die Stahllegierung zeichnet sich durch einen Stickstoffgehalt von 0,003 bis 0,01 % aus und enthält außerdem 0,010 bis 0,040 % Titan und 0,001 bis 0,03 % Bor, mit einem Ti/N - Verhältnis von mindestens 3,4.
